Automobile airbags inflate due to the formation of nitrogen gas from the chemical reaction 2NaN3(s)⟶3N2(g)+2Na(s) Identify the n
Vera_Pavlovna [14]

<u>First part:</u>

2 atoms of Na

6 atoms of N

<u>Second part:</u>

2 atoms of N

2 atoms of Na

Why?

We are given the chemical reaction, so, we can extract the number of atoms for both reactants and products.

We are given the chemical equation:

2NaN_{3}=3N_{2}+2Na

We can rewrite it as follow:

2(NaN_{3})=3N_{2}+2Na

From the reactants, we have:

2(NaN_{3})

2Na=2atoms\\2N_{3}=2*3=6atoms

From the products we have:

3N_{2}+2Na

3N_{2}=3*2=6atoms

2Na=2atoms

Hence, we have that:

There are <u>6 atoms of N in the reactants</u> and <u>6 atoms of N in the products.</u>

and

There are <u>2 atoms of Na in the reactants</u> and<u> </u><u>2 atoms of Na in the products</u> since we have a balanced equation.

Have a nice day!

What characteristics of sodium and chlorine atoms allow them to form the stable compound sodium chloride, Also known as table sa
katrin2010 [14]
Atoms 'like' to have 8 valence electrones. sodium has one electron 'in excess' and chlorine 'lacks' in one. so they just exchange :) both are happy. then the ionic bond is formed because chlorine is now charged negative (additional electron) and sodium is charged positive (gave up one electrone) - the opposite charges cause electrostatic pull. many atoms, many bonds and thats how salt is built.

Explain the role of molecular geometry in determining molecular polarity
Ede4ka [16]
The molecular geometry of a compound helps to determine polarity b/c, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs b/c if there are no lone pairs on the central atom, then it is nonpolar.
